Plaas catches the cable and pulley disease...

I'm blaming it on Ed. That's my story and I'm sticking to it.

The z-axis is working fine and I'm working on getting the x-axis cranking. I was at the hardware store and saw all the nice little nylon pulleys for curtains....

...then I got to thinking that I'd only bought just enough of the Frankenmotors for Godzilla and I really needed some spares. Being of Scots-Irish ancestry I got to thinking that a cheap way to get spare motors is to not need so many in the design...

...and since the Frankenmotors have enough torque to run 5-6 axes each, never mind one. That, of course, hooked up nicely with the idea that if you only have one motor per axis you don't have to solve the problem of making two motors run in tandem...

...and away I went. Half an hour with my whiteboard and markers and I have a plan.
